A __________________ is used to visually describe the acoustic signal of speech by plotting frequency as a function of time.
A) speech spectrogram
B) voice onset graph
C) formant grid
D) sound map

Question

Quizplus · Accepted Answer

A speech spectrogram is the best choice as it is a visual representation of the frequency components of speech over time. A voice onset graph is a tool used to analyze the timing and coordination of vocal fold vibration during speech production. A formant grid is also a visual representation of speech sounds, but it is used to display the formant frequencies of vowel sounds in relation to each other. A sound map is not related to the analysis of speech signals.
